Quite recently I had a discussion with experts in geosciences about using GPGPUs for the computations. One questions that you usually get when talking about GPGPUs is why GPUs and not just invest on supercomputers based on CPUs.
Well, I provided couple of reasons, such as accessibility, power consumption, costs per computing core, etc. I also came upon this article “Why Nvidia’s chips can power supercomputers?” on CNet News (click here).
I found it quite interesting in explaining some of the reasons. I hope you will enjoy it as much as I did.
